TO SUMMON A DEMON HELPER
Time:
Midnight on a Saturday.
The dark of the Moon. Place:
Cemeteries, Haunted Places, etc.
Items needed:
black candles,
brimstone (or any other "dark" type incense, black arts etc.)
black onyx (Black Onyx was believed to already possess a spirit so this is why I use it but you can choose any black stone of your choice.)
Sterilized needle.
Disrobe.
Arrange black candles in any pattern one may wish, pentagram or what not.
(I use graveyard dirt to draw a pentagram and then place black candles at each cross point.)
Light the brimstone as incense.
At midnight chant:
"IT IS MIDNIGHT.
THE GATES OF HADES ARE OPENED AND DARKNESS IS UPON THE LAND"
*3X Hold the stone in your left palm.*
"I CONJURE THEE DEMON BY THE POWER OF THY NAME;
ABSHALLAH NEJAR SEPTIA,
AS FLESH CLINGS TO BONE SO YOU TO STONE!
*If done properly you should see with your mind's eye a purplish "lightning" dance around the stone.*
*You must never let sunlight hit the stone or the spirit will return from which it came.*
*You can ask of your demon anything but alas, it seems that the relationship is not permanent.*
*If you demon fails to comply with your wishes it may be time to exile it.*
*I've notice that threatening to place the stone in the sun sometimes works to "compel" the entity but if it becomes violent immediately cast it out into the daylight.*
*You must reward the demon by feeding it three drops of your blood after if fulfills any of your wishes.*

Ok maybe a bit late but I must agree with Ashnook. The whole ritual is forced to be to dark. But I have a question for you. Are you a Christian? I would bet not, so why can you summon a demon and work with it? For that to be true you have to believe in God in all his Christian form as well.
When you work with demons and angels you work with your own emotions and feelings.
I am sorry to say but the ritual sounds something out of a dungeons and dragons story, brimstone? graveyard dirt?
There are many ways of working with demons, angels and other emotions that work well and do involve walking at night over someones grave.
